Farting is something everyone has, everyone farts every day, this is due to the fact that while eating there is also part of the gas that enters the gastrointestinal tract with the food, plus the fermentation of the food under the action of the intestinal bacteria also produces part of the gas, and these gases are discharged out of the body with the stools to form a fart. So farting in the evening may be due to the fact that it is related to what you eat in the evening, for example, you often eat some food that produces more gas in the evening: soybean products, radish, onion, high-sugar food and so on. There may also be gastrointestinal disorders that lead to intestinal flora imbalance, causing more gas production from fermented food. It can be improved by improving dietary habits, eating light, less gas-producing food, and at the same time can be added with some drugs to regulate intestinal flora.
